Please try the latest version. Does grub-probe detect the correct modules now? If not, please tell me how can I reproduce this on a normal PC. I have tried to setup /boot as LVM in D-I, but it won't let me. > lsmod reported that the raid and lvm modules were definitely loaded. > Attempting to do "insmod normal" resulted in the "error: unknown > device."

Does this still apply? Was the "pc" module listed by lsmod? What happens if you do "set debug=all" and then insmod normal? Can you obtain the full log via serial cable?

Please can you try with latest grub-probe?
